Kelulut Bees is a stingless bee that produces honey, in the area of Gunung Nyiut Nature Reserve Kelulut Bees lives naturally with nests on tree trunks. It is not yet known how the habitat and sources of feed so that it is necessary to do research on the study of habitat and feed sources of Kelulut Bees. This study aims to obtain information about the condition of habitat and feed sources of Kelulut Bees. The method used was a survey with double plots which purposively placed, then identified the condition of habitat and feed sources. Types of hornet bees found were: Heterotrigona itama, Tetragonula laeviceps, Geniotrigona thoracica, Trigona carbonaria and Trigona drescheri. The bees nesting place were in living trees is (52%), dead trees (20%) and soil (28%). Daily mean temperature, air humidity and light intensity were 28.81 °C, 83.06%, and 583.76%. Soil type is PMK with pH 4.4, soil temperature 26.6 C °, soil moisture 26%. Altitude ± 360 masl. Tree analysis was dominated by Xanthophyllum amoenum 36.38%, Lepisanthes tetraphylla 38.01%, Syzgium chloranthum 45.8%, and Bellucia pentamera seedlings 51.58%. The feed sources at the observation sites were dominated by the family Myrtaceae and Dipterocarpaceae, while outside the plots the feed source was dominated by Cocos nucifera L, Durio zibethinus, Nephelium lappaceum L, Syzygium aqueum.Keywords : Feed source, Gunung Nyiut, habitat, kelulut bees, Nature Reserve.

Bamboo has been known by people for generations and has good properties to be used. The purpose of this study was to identificated types of bamboo that grow in Tembawang Forest of Tekalong and obtain data on the utilization of bamboo carried out by the people of Tekalong,  Setia Jaya Village, Teriak District, Bengkayang Regency. The method used in this study is a survey method. Data collection techniques, with observation and interviews using the help of a questionnaire. Sampling at the research location was done by purposive. The sampling technique for bamboo at the study site was using double plots measuring 5 mx 5 m.The amount of bamboo found in 4 areas of Tembawang Forest in Tekalong are 6 types of 3 different genera namely the genus Schizostachyum, Gigantochloa and Bambusa. The types of bamboo include: kayan (Schizostachyum flexuosum Widjaja), gare (Schizostachyum brachycladum Kurz), tarenk (Gigantochloa hasskarliana (Kurz) Backer ex Heyne), bangking (Gigantochloa balui K.M. Wong), betung (Gigantochloa levis (Blanco) Merr.), aur (Bambusa vulgaris Schrad ex Wendl). Bamboo in Tekalong can be used as raw material for making handicrafts, traditional ceremonies, making lemang, consumed and other benefits.Keywords :Identification, Bamboo, Utilization, Tembawang Forest

There is a long history of the plant's usage as medicine to overcome various diseases and maintain people's health conditions in communities.  Among its multiple benefits, medicinal plants are also used to strengthen the body organs (tonic). The use of medicinal plants as tonics is still carried out by the society of Karya Bakti Village, Sungai Betung District, Bengkayang Regency, especially by traditional healers (dukun) who are trusted by the community to help treat various diseases. This study aims to analyze plant's use by traditional healers in Karya Bakti Village, Bengkayang Regency. The data was collected by interviewing two traditional healers who were selected based on the snowball sampling technique. The interview results revealed that the village's traditional healer used 32 species of medicinal plants belonging to 25 families. The most widely used plant family is Zingiberaceae (19%), with the highest habitus is herbs (31.25%). The most commonly used part is the root (28.13%), the form of single ingredients (53%) by boiling processing (74.36%), the administration is orally (77.5%) with a frequency of use three times a day (75%). The study results proved that traditional healers in Karya Bakti Village were still using medicinal plants as tonics.Keywords: medicinal plants, tonic, traditional healers

75 PERBANDINGAN TINGKAT KEAWETAN KAYU SENGON (Falcataria moluccana L. Nielsen) DAN KAYU SUGI (Cryptomeria japonica D. Don) DENGAN EKSTRAK LIMBAH KULIT KAYU JATI (Tectona grandis L.F.) TERHADAP SERANGAN RAYAP TANAH Coptotermes curvignathus Holmgren AbstractThe aim of the study was to obtain a comparison of the durability of sengon (Falcataria moluccana) and sugi wood (Cryptomeria japonica) after preservation with Jati (Tectona grandis) tree bark waste to subterranean termites Coptotermes curvignathus Holmgren attack and to determine the best concentration of wood preservation from Jati extract. Evaluation the durability of wood used the JIS K 1571 2004 standar method. Test parameters in the study were preservative retention, termite mortality and weight loss of the wood test sample. The results showed the highest retention was achieved in Sengon wood of 0.466 kg /m 3 and the followed by Sugi wood which was 0.740 kg /m 3 . The lowest termites mortality value was in non-teated wood of Sengon wood with value 13.091%, and in other sengon wood which treated by extract of Jati bark with concentration of 2%, 4%, 5%, the termites mortality was 100%. Meanwhile in Sugi wood the termites mortality in non-treated wood was 12.576% and other Sugi wood which treated by extract of Jati bark with concentration of 1%, 2%, 3%, 4%, 5% the mortality value reached 100%. The average percentage values of the highest weight loss was 15.483% in nontreated sugi wood, while the lowest weight loss was in sengon wood which was given 5% extract of teak bark with a concentration of only 2.099%. The optimal concentration of Jati tree bark for wood preservation to Sengon wood was on concentration 25, meanwhile in Sugi wood was on concentration 1%. PENDAHULUANJenis kayu fast telah dimanfaatkan sebagai bahan baku bangunan, furniture, mebel, kerajinan dan berbagai produk lain. Kayu fast growing memiliki kelas awet yang rendah, sekitar 80-85% kayu-kayu Indonesia memiliki keawetan rendah yang mudah diserang oleh organisme perusak kayu (Yunasfi, 2008). Jenis kayu yang memiliki keawetan rendah dan sering dimanfaatkan adalah kayu sengon (Falcataria moluccana). Pohon sengon dapat mencapai tinggi sekitar 30 -45 meter dengan diameter batang sekitar 70 -80 cm, berat jenis kayu sengon rata-rata sekitar 0,33 dan termasuk kelas awet IV -V (Wiryadiputra, 2007). Berbeda dengan di Indonesia, di Jepang kayu dengan kelas awet rendah yang sering digunakan adalah kayu sugi (Cryptomeria japonica). Kayu sugi memiliki kelas awat rendah yaitu termasuk ke dalam kelas awet III JURNAL TENGKAWANG (2018) Vol. 8 (2) : 75 -87

The aim of the research was to examine the antifungal activity and the most effective concentration of teak bark (Tectona grandis Linn F) extract in inhibiting wood decay fungi Schizophyllum commune Fries. Teak bark was derived from BKPH Ledok, Sambong district, Blora Regency, West Java. The Teak bark made into particle with size pass of 40 mesh and retained 60 mesh. Then one kilogram of teak bark particle was maceration with 10 liter of aquadest. The extract then mixes with potatoes dextrose agar (PDA) with several concentration i.e. 0%, 0.25%, 0.5%, 0.75% and 1% and pour into petri dish. One isolate of Schizophyllum commune was put in the center of PDA in each petri dish then incubated for nine days. The bioactive compound of extract teak bark was evaluation used phytochemical screening. Result of the research showed that teak bark extract at concentration 0.25% and 0.5% has antifungal activity values was 27.98% and 40.38% and categorized as medium inhibition growth of S. commune. Meanwhile at concentration 0.75% and 1% the AFA values was 59.94% and 65.51% categorized as strong inhibition growth of S. commune. The bioactive compounds from phytochemical screening test were alkaloid, flavonoid, terpenoid, fenolik, antrakuinon, and saponin. The extract of teak bark with concentration 0.75% and 1% are the most effective concentrations in inhibiting the growth of wood decay fungi S. commune Fries.Keywords : antifungal, phytochemical screening test, Schizophyllum commune, Tectona grandis
